Panchang in Codcod, Western Visayas, Philippines Sat 11 Aug 2007

Shiva’s worship centres on nishitha, the midnight muhurta. Chaturdashi runs from 07:51 on Sat 11 Aug to 07:12 on Sun 12 Aug, so only Saturday night’s nishitha (23:29–00:15 Sun) falls within it. No text giving Masik Shivratri’s time was found; nishitha is Tithika’s convention.

Masik Shivratri: every date in Codcod

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 324°–336° is the 28th, Krishna Trayodashi. A day takes the tithi in force at its sunrise, 05:37 here. Dwadashi ended at 08:56 Fri, before it. Trayodashi ends at 07:51, when the lead reaches 336°. The lead passed 180° at the full moon of 30 Jul, so the Moon is waning: Krishna paksha.

The night of Fri 10 Aug ran from sunset 18:08 Fri to sunrise 05:37, 11 h 29 m. Cut into 15 muhurtas of 45 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 05:37 to 18:07, splits into 8 choghadiyas of 1 h 33 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 18:07 to 05:37 Sun, splits into 8 choghadiyas of 1 h 26 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Punarvasu spans 80°00′–93°20′; the Moon entered its pada 3 at 86°40′. It leaves at 13:49, for Pushya.

Add the Sun's and the Moon's places among the stars: 113.9° + 88.7° = 202.6°. The sum, cut into 27 parts of 13°20′, gives the yoga: 200°00′–213°20′ is the 16th, Siddhi. It ends at 23:30, then Vyatipata.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Trayodashi is Garaja and the second Vanija. Garaja ended at 20:21 Fri, when the lead reached 330°; Vanija runs until 07:51.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 05:37 to 05:37 Sun, so the hours after midnight still belong to Shaniwara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mithuna gives Ashadha. The Sun enters Karka on 17 Jul, inside the month. The next new moon, 13 Aug, finds it in Karka and begins Shravana.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 13 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 19 Mar 2007, 10:42 Mon. Since then the Sun has moved 139.7° round the stars. Vikram Samvat numbers that year 2064; Shaka Samvat numbers it 1929.
